We are pleased to present this year's Annual Water Quality Report (Consumer Confidence Report) as required by the Safe Drinking Water Act (SDWA). This report is designed to provide details about where your water comes from, what it contains, and how it 11 compares to standards set by regulatory agencies. This report is a snapshot of last ear's water quality. We are committed to providing you with information because informed customers are our best allies. �• _� -Do I need to take special precautions? P A.— Some Some people may be more vulnerable to contaminants in drinking water than the general population. Immuno -compromised'> persons such as persons with cancer undergoing chemotherapy, persons who have undergone organ transplants, people with HIV/ AIDS or other immune system disorders, some elderly, and infants can be particularly at risk from infections. These people should seek advice about drinking water from their health care providers. EPA/Centers for Disease Control (CDC) guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbial contaminants are available from the Safe Water Drinking Hotline (800-426-4791). -Why are there contaminants in my drinking water? qy Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. The presence of contaminants does not necessarily indicate that water poses a health risk. More information about contaminants and potential health effects can be obtained by calling the Environmental Protection Agency's (EPA) Safe Drinking Water Hotline ( (800-426-4791). -Additional Information for Lead 1 If present, elevated levels of lead can cause serious health problems, especially for pregnant women and young children. Lead in drinking water is primarily from materials and components associated with service lines and home plumbing. City of Chubbuck is ✓�%. responsible for providing high quality drinking water, but cannot control the variety of materials used in plumbing components. A When your water has been sitting for several hours, you can minimize the potential for lead exposure by flushing your tap for 30 seconds to 2 minutes before using water for drinking or cooking. If you are concerned about lead in your water, you may wish to -Additional Information for Nitrate have your water tested. Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available from the Safe Drinking Water Hotline at http://www.epa.gov/vour-drinking-water/safe-drinking-water-hotline Nitrate in drinking water at levels above 10 ppm is a health risk for infants of less than six months of age. High nitrate levels in drinking water can cause blue baby syndrome. Nitrate levels may rise quickly for short periods of time because of rainfall or agricultural activity. If you are caring for an infant, you should ask for advice from your health care provider. -Source water assessment and its availability The state has completed an assessment of our source water. That report is available for review at the City Offices. -How can I get involved? F The City has attempted to make this report informative and readable.
